python 发送邮件

使用qq邮箱发送邮件，需要申请qq邮箱授权码

# coding=utf-8
import smtplib,sys
from email.mime.text import MIMEText

class Msmtp():
    def __init__(self, target, subject, content):#收件人、标题、内容
        self.msg_from = '发出邮件的邮箱'
        self.password = '邮箱的授权码'
        self.sender = smtplib.SMTP_SSL("smtp.qq.com", 465)
        self.msg_to = target
        self.subject = subject
        self.content = content

    def _login(self):
        self.sender.login(self.msg_from, self.password)

    def _msg(self):
        self.msg = MIMEText(self.content)
        self.msg['Subject'] = self.subject
        self.msg['From'] = self.msg_from
        self.msg['To'] = self.msg_to

    def send_mail(self):
        self._login()
        self._msg()
        self.sender.sendmail(self.msg_from, self.msg_to, self.msg.as_string())
        self.sender.quit()



if __name__ == '__main__':
    a = Msmtp(sys.argv[1], sys.argv[2], sys.argv[3])
    a.send_mail()
